Shell medium-sized, turbinate-conic, rather thin. Whorls 

 about six, shouldered; shoulders furnished with a spiral cord, the 

 surface above the cord being slightly excavated (a character not 

 distinct in younger whorls), below somewhat convex with four 

 narrow spiral grooves. These grooves make the interspaces look 

 like broad flattish spiral cords of which the third from above is some 

 what broader and more elevated than the others. Lines of growth 

 elevated and prominent on the younger whorls, looking like long- 

 itudinal striations. On the l)ody-whorl these lines are not so 

 prominent, though quite coarse. Periphery rounded. Base convex 

 with several iiiequidistant spiral grooves. Umbilical margin round- 

 ed. Umbilical wall with several spiral grooves, the spaces being 

 convex, cord-like and often made crenate by coarse lines of growth.

 millirn. Diameter 12 millim. 



The original colour of tlie shell is present on mnny specimens 

 as brown longitudinal streaks.
